Ой-ой! Структура данных хэш-таблица (HashMap) предназначена ля быстрого поиска значений по ключу. Метод get(K key) находит значение, или проверяет, что его нет за O(1). Вы пытаетесь пройти по всем ключам в обход стандартных методов мапы, это говорит о том, что вы не посмотрели, как она работает.
Задание - разобраться в HasMap, материалы есть в блоге. Это основная структура данных.
Object getByName(String name) {
return objByName.get(name);
}
Где-то я уже видел подобный код...
